What is vulcanization of rubber

Explanation:
Vulcanization of rubber is the process of converting natural rubber to more strong and elastic form.
Natural rubber is mixed with 3 to 5% sulphur and heated at 100 to 150 ℃ to form cross linking of cis−1,4−polyisopropene chains through disulphide bonds.
